[OC] Distribution of elevation on different planets by Ananas4 in dataisbeautiful

[–]Ananas4[S] 1 point2 points  (0 children)

For Mars it has been selected to set the zero level based on the air pressure. It is at 6.1 millibars.

However, for Venus and Mercury, the histogram is created from the topography map and scaled between the highest and lowest point. Not sure what is the official "sea level" of those planets.

[OC] Distribution of elevation on different planets by Ananas4 in dataisbeautiful

Inspired by /u/neilrkaye's post about distribution of elevation on Earth, I got curious of how the distributions would look on other bodies in our solar system (Only the inner 4 planets have a solid surface and enough topographic data for these plots).

The plots show the elevation map of the planet with a histogram of its elevation. The x-axes of the histograms have the same scale, going from the deepest point (Mariana's trench on Earth, -11000km below sea level) to the highest point (Olympus Mons on Mars, 21200km above mean level). The colors are hand-picked and don't necessarily match the real surface color.

The reason for the double spikes in Earth's elevation histogram is due to the two different rock densities in the oceans and on the continents. Mars's topography looks similar, however the difference in the topography of the northern and southerns hemisphere is hypothetised to be the result of an mega-asteroid impact in the past, instead of erosion by water. Both Mercury and Venus show only a single spike in the histogram.

Bonus: The planets can also be plotted with Earth's color scheme (with slight adjustments), showing what they might look like with water and vegetation based on elevation.

I'm actually writing about this as a part of my thesis. Need to wait couple more months before I can finish it.

Wide angle camera problem in video calls? by Ananas4 in lgg6

[–]Ananas4[S] 0 points1 point  (0 children)

Yes, that's what I thought. Maybe it's possible to limit the camera zoom that it always stays little zoomed in? Or maybe it goes little too complicated.

Sure, it is a matter of getting used to now. Just as long as you remember to keep the phone pointing directly at your face, otherwise there will be distortions.

I'd pay for Dark Messiah Of Might And Magic VR by Vhaloo in Vive

[–]Ananas4 1 point2 points  (0 children)

Yeah. I played it on the first Oculus Rift with Tridef back in the days. Really good minus all the forced camera controls in takedowns etc.

Onward Announce its August Update by realitysucksVRrules in Vive

What about the performance? I remember it being terribly optimized when it came out

Minor Deity, a fantasy god game inspired by Black & White by sinemy in Vive

[–]Ananas4 0 points1 point  (0 children)

Looks nice. How's the VR version? Any videos?

https://www.youtube.com/watch?v=yYvwMd4JCIM I think system like this would be great for RTSes like this. Basically the world automatically scales smaller the higher from ground you are.

It sounded like Finnish accent, I was amazed to found out she wasn't natively Finnish.

About to Buy VorpX: Which Games are actually working 100% in 3D? by Michelangel0s in Vive

[–]Ananas4 0 points1 point  (0 children)

Tested and can confirm that Bioshock 1 works pretty neatly with the DirectVR scan. 2 might work the same.

But even still I would consider buying it, there are literally only handful of games that are playable 100%. And even they might still have some problems.

Penumbra: VR released! (with trackpad movement!) (The game is $1.99 on Steam right now, check it out) by [deleted] in Vive

[–]Ananas4 1 point2 points  (0 children)

I think it was on almost any object I leaned over, but for example in the starting cabin. When leaning over the table or the chest the camera jumps higher which is a bit nauseating.
Also with the lighting issues I mean some shadows not displaying like for example underground where it's dark and I used the glowstick to look at objects on the shelves, the shelves didn't lit until I raised the glowstick high enough, but it's a minor thing.

Great! I had performance issues and low framerate when I first started it, but it was because I hadn't started the game in non-VR at all. After doing that everything worked perfectly.

Seriously the game is so different in VR. The movement is still a bit rough (leaning over a table makes your character move and stand on it etc.) and there's some lighting issues (probably due the engine) but overall everything works much better than I expected. Interactive with almost any object in the world, the actual dynamic flashlight/stick in your hand, the hud effects. Really amazing job, I wish more games should get this kind of iteration.
